1 Getting Started
The PK202-25 is an extremely bright PLED display, that features a 160 degree viewing angle and is
designed to decrease development time by providing an instant solution to any project. With the ability to
communicate via serial RS-232/TTL and I2C protocols, the versatile PK202-25 can be used with virtually
any controller. The ease of use is further enhanced by an intuitive command structure to allow display
settings such as backlight brightness, contrast and baud rate to be software controlled. Additionally, up to
thirty-two custom characters such as character sets for bar graphs, medium and large numbers may be stored
in the non-volatile memory to be easily recalled and displayed at any time. The PK202-25 comes in extended
voltage, and temperature options to allow you to select the display which will best fit your project needs.
